摘要：A method for producing a polarizing glass wherein a glass preform containingmetal halide particles having a prescribed particle size dispersed therein is heated to aprescribed temperature and elongated, to thereby form a glass sheet containingelongated metal halide particles, and then said metal halide particles are reduced to themetal, characterized in that the glass sheet having been heated and elongated is
quenched and then subjected to an annealing treatment, and thereafter, the above metalhalide particles are reduced to the metal. The method allows the removal of the stresswhich generates during the above heating and elongating treatment and residues in theglass sheet, without the reduction of the extinction ratio of the resultant glass sheet,which results in the production of a polarizing glass having good optical characteristics ata low cost.
